RE: 28% edge pics
I trimmed it out with Monokote and used lusterkote to paint the red on the cowl and then had the metallic charcoal color matched at the local automotive paint store, I think it ended up being a match on a 1994 toyota bumper. Then cleared it with Lustekote clear.
About the only covering I did not remove was on the rudder and elevators. The rest I removed and redid with white ultracote, I just wanted the lines and seems to look a little better.
